Abstract:

By providing coding ability at intermediate nodes, network coding has been shown to improve network throughput in broadcast/multicast wireless networks. In this paper, we show that by imposing coding structure, network coding can be further optimized specifically for video streaming in a rate-distortion manner, in a scenario where wireless adhoc peers cooperatively relay packets to each other to repair packet losses during MBMS broadcast. Experimental results show that our proposed scheme can improve video quality noticeably, by up to 19.71dB over un-repaired video stream and by up to 7.90dB over video stream using traditional unstructured network coding.
